How to access a website running on my localhost(host/server) to Serial Monitor using ESP8266(Client)?

Question

The following source code is from the official ESP8266 website(Explanation provided): https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/client-examples.html
This .ino code returns the html code of the server name mentioned in "const char* server" declaration, on to the Serial Monitor.

And Yes, this code perfectly returned the html codes of wwww.google.com, www.arduino.cc etc. But when I try it with my 'led blinking.html' I am unable to find any luck. I guess it is because the website should be hosted on a live server.

Other Details:
1. uC Board: Wemos D1 mini (An ESP8266 Variant)
2. I am using Xampp to run Apache server and MySQL
3. Wemos board is set up as a WiFiClient

#include <ESP8266WiFi.h>
const char* ssid = "xxxxx";
const char* password = "xxxxxxxx";

I have put the html,php code of the website in the directory : C:/xampp/htdocs/LED BLINKING/led blinking.html

IP Address of my Windows PC: 192.168.100.9

const char* server = "192.168.100.9/LED BLINKING/led blinking.html";

I tried with just "192.168.100.9"; too. I also unblocked the windows firewall for my ApacheHTTP Server. Now I can view the webpage on my mobile with the URL: 192.168.100.9/LED BLINKING/led blinking.html.

void setup()
{
 Serial.begin(115200);
 Serial.println();
 Serial.printf("Connecting to %s ", ssid);
 WiFi.begin(ssid, password);
 while (WiFi.status() != WL_CONNECTED)
 {
 delay(500);
 Serial.print(".");
 }
 Serial.println(" connected");
}
void loop()
{
 WiFiClient client;
 Serial.printf("\n[Connecting ...");
 if (client.connect(server, 80))
 {
 Serial.println("connected]");
 Serial.println("[Sending a request]");
 client.print(String("GET /") + " HTTP/1.1\r\n" +
 "server: " + server + "\r\n" +
 "Connection: close\r\n" +
 "\r\n"
 );
 Serial.println("[Response:]");
 while (client.connected())
 {
 if (client.available())
 {
 String line = client.readStringUntil('\n');
 Serial.println(line);
 }
 }
 client.stop();
 Serial.println("\n[Disconnected]");
 }
 else
 {
 Serial.println("connection failed!]");
 client.stop();
 }
 delay(5000);
}

The output on Serial Monitor is: Connecting to ssid connected [Connecting connection failed!]

Variable server is a hostname or IP address for TCP connection. The /LED BLINKING/led blinking.html goes after HTTP GET. Now there is / and it worked for main page of servers.

You need

client.print(String("GET /LED%20BLINKING/led%20blinking.htm") + " HTTP/1.1\r\n" +
 "server: " + server + "\r\n" +
 "Connection: close\r\n" +
 "\r\n"
 );

and you must escape the space
